Paul Millander
> Show: CSI: Crime Scene Investigation (2000-2015)

Like most police dramas, “CSI: Crime Scene Investigation” portrayed many serial killers and other sociopaths over the 15 years it was on TV. One of the most memorable was Paul Millander, who the public knew as Judge Douglas Mason. Millander was the archenemy of Gil Grissom, the scientist and CSI supervisor played by William Peterson. Millander kills people and stages the scene to look like a suicide, mimicking his father’s murder.

The Gravedigger haunted Booth, Brennan, and the rest of the “Bones” team over several of the early seasons of the series.

Brennan eventually realizes the Gravedigger was state attorney Heather Taffet, who used her position to throw investigators off the case.
